The factory table base and table legs are from a company called ITC Manufacturing. The current model used is the Sequoia III. I replaced our boats original Sequoia II leg and base that was originally supplied on my 2017 C-28. I upgraded because the former owner lost the Sequoia II table leg. The Sequoia II and III are not compatible. Sequoia II parts are no longer available from ITC.
The Sequoia III base required drilling five new 1/4” holes through the bilge hatch and securing them with 1 1/2” long stainless bolts, large stainless fender washers and nylon insert stainless nuts. The Sequoia III base is quite a bit bigger than the II base. The old holes from the Sequoia II base were filled with marine sealant.
The height of the table leg used is 25.5”.
ITC Manufacturing also sells table tops but lots of others make wood table tops of different sizes and shapes.
